Fabricated Test Cables
Several of the test cables to make the connections from the XLR connectors of
the AM700 to the different connectors of various test equipment are fabricated
specifically the AM700 verification and adjustment procedures. If the verifica-
tion procedures you want to perform call for one of these cables, you must
fabricate it or a similar cable to make the connections. Figure provides a guide
for use in making the special connector cables.
